False positive unused warning with import alias

[lenguyenthanh]

Compiler version

3.3.0-RC5

Minimized code

//> using scala "3.3.0-RC5"
//> using options "-Wunused:all"


case class Foo(x: Int)

val foo = Foo(1)

@main def main =
  import foo.{x as y}
  println(y)

Output

Compiling project (Scala 3.3.0-RC5, JVM)
./UnusedImport.scala:10:15
 unused import
   import foo.{x as y}
1

Expectation

It shouldn't report any warning as the import is being used.
